Nasai

(1) The tribe of Abd al-Qays resided in Bahrain, which at that time was considered part of Yemen. In the region of Yemen during that period, intoxicating drinks were widely consumed; therefore, the Prophet (sallallahu alayhi wa sallam) gave them special instructions.

(2) “With a cut mouth” — because if the mouth is cut, it becomes like a jar and its mouth cannot be tied, thus it would not be possible to detect intoxication in it. When the mouth of a waterskin is tied, if intoxication develops in the nabidh, the waterskin bursts, thereby revealing the presence of intoxication. For this reason, the Prophet (sallallahu alayhi wa sallam) commanded that the mouth of the waterskin containing nabidh be tied.

(3) “Drink it while it is sweet” — meaning, its taste should not have changed, because if its taste changes, there is a possibility of intoxication.

(4) “Grant permission” — this person also spoke by gesture, and the Messenger of Allah (sallallahu alayhi wa sallam) also replied by gesture. The exact determination of this gesture is impossible, but the meaning is as stated in the translation: he sought permission to drink nabidh that was either prohibited or at least doubtful, and the Prophet (sallallahu alayhi wa sallam) did not grant permission due to the presence or risk of intoxication. And Allah knows best.
